“…A Photron FASTCAM SA5 high‐speed camera with a color sensor is used in 2010 and its sampling rate is set at 10,000 fps. F1004, the Case 7 in Lu et al [2011], is a flash with two RSs occurring in the viewing range of this camera. Two high‐speed images of F1004 captured by the color SA5 are shown inFigures 2a and 2b.…”

[1] Forty-five unconnected upward leaders (UULs) occurred in 19 downward negative flashes are analyzed. Each observed UUL is initiated by a downward stepped leader before a new strike point is struck. For each UUL, several parameters are determined when possible mainly by using high-speed images: inception height, inception time prior to return stroke (RS), horizontal distance from the flash's strike point, two-dimensional (2D) distance between the nearest downward leader branch tip and the UUL's inception point at its inception time, 2D length, and 2D average propagation velocity.
